Morton, Tony Award nominee and star of Signature's Chess, wrote an apology on Facebook after announcing the cancellation.

"I have been offered (and with Signature's blessing, accepted) a job at Yale Rep Theatre in New Haven. It's an exciting, funny play and with only a cast of two (playing numerous characters) it was too good a challenge to turn down. These are the kinds of projects an actor lives for. It tore me up to give up the chance to share beautiful music with you all this time around. However the scheduling was a direct clash with the concert dates and no alternative could be found. I'm so very sorry. This has never happened in my music career before. I hope you can understand and will come hear me next time time Signature has me back - which they've assured me they will do!"
